Hello everyone! I've recently moved and have been having some troubles. About 2 or 3 days ago, when I tried playing Champions Online my computer would shut off after 20 minutes in. I had never played the game previous to the crashes, so not sure what the deal is. After that, I just uninstalled it and went to playing my normal games. I play League of Legends and was in the RIFT beta. In a League game, my computer suddenly crashed again without notice and continues to crash sometimes. Other times it plays perfectly fine through 45 minutes - 1 hour long games. The weird thing is, I hopped on RIFT after a crash once and I had it going for about 3 - 4 hours straight, no crashes. I used to play 4 - 5 games a day of League before I moved, so it has run it perfectly fine before. The computer is not overheating. It barely goes past 30c and maybe reaches 35c when playing games. Everything is up to date, so really not sure what the problem is. It ONLY crashes during League of Legends, not sure of other games as I don't play any others except Runescape, which is browser based and doesn't crash the computer. AMD Athlon(tm) 64 X2 Dual Core Processor 4000+ 2.11 GHz, 2.00 GB of RAM Physical Address Extension ATI Radeon HD 4650 Windows XP Family The power supply is only a year old, maybe not even yet. If I missed anything then please let me know what I need to tell you and how I can find it out. Thank you!
